Serial D-dimer measurements dynamically predict disease severity in acute biliary pancreatitis: a prospective observational study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background/aim: Early risk stratification is required in cases of acute biliary pancreatitis (ABP). Traditional scoring systems such as Ranson's criteria are complex and often delay treatment. D-dimer, a basic marker of systemic inflammation and coagulation, has shown promise as a prognostic tool. The present study investigates whether the predictive accuracy of serial serum D-dimer measurements is superior to that of the Ranson and BISAP scoring systems for moderate-to-severe ABP. Materials and methods: Included in this single-center prospective observational study were 264 patients diagnosed with ABP between July 2022 and July 2025 whose collected data were analyzed. The participants were categorized as mild, moderate, or severe based on the current Revised Atlanta Classification (2012), and D-dimer levels were measured at admission (H0), 24 h (H24), and 48 h (H48), along with their BISAP scores to allow a comparative analysis. Results: Mean D-dimer levels increased significantly with disease severity at all timepoints (p < 0.001). ROC analysis identified the D-dimer level at H48 to have the highest discriminative value for predicting moderate-to-severe ABP (AUC: 0.812; 95% CI: 0.758-0.866). The H24 and H0 D-dimer levels also performed well (AUCs: 0.728 and 0.719, respectively). In comparison, the Ranson (H48 AUC: 0.741) and BISAP scores (H24 AUC: 0.755) yielded lower predictive accuracy - the H48 D-dimer AUC being statistically superior to both (p < 0.05). Conclusion: Serum D-dimer levels are significantly associated with ABP severity and show promise as a practical, accessible, and cost-effective adjunctive biomarker for early risk assessment. Serial measurements, especially at 48 h, offer superior diagnostic accuracy compared to Ranson and BISAP scoring alone. The clinical measurement of D-dimer levels at 48 h can thus be considered an accessible and timely triage approach. Multicenter prospective validation studies are needed to confirm the diagnostic thresholds and to assess clinical integration.
